A proper planting system and efficient management are needed to cultivate forage effectively. Therefore, this research aimed to evaluate forage production and nutrient content of different elephant grass varieties grown with Indigofera in the intercropping system and were harvested at different intervals of defoliation. The research was conducted in the dry and rainy seasons using a randomized block design with 3 factors (2x2x2) and 4 replications. The first factor was two different elephant grass varieties consisting of cv. Pakchong and Taiwan, the second factor was the planting pattern, including intercropping and monoculture, while the third factor was harvesting age, comprising 50 days and 60 days. The results showed an interaction effect between grass varieties, planting patterns, and harvesting ages. Intercropping the Pakchong varieties with Indigofera and harvesting at 60 days produced the highest forage fresh weight and DM production, ADF as well as NDF contents and yields, CP yield, and the highest carrying capacity (p<0.05) according to DM intake. When harvested at 50 days, Indigofera increased the protein content of forage, but this effect did not occur when it was harvested at 60 days. Furthermore, nutrient yields were not affected by interactions of three factors in the rainy season (p>0.05), but in the dry season, the highest ash and CP yields were produced by the Pakchong variety intercropped with Indigofera and harvesting at 60 days. The highest ADF and NDF yields were obtained from the Taiwan varieties grown in monoculture and harvested at 60 days. Based on the results, it was concluded that the two varieties of elephant grass could be cultivated with Indigofera in the intercropping system and harvesting time of 60 days will produce the highest nutrient yield and carrying capacity.
正确的种植制度和高效的管理是有效培育饲草的必要条件。因此,本研究旨在评估间作系统中用靛蓝种植的不同象草品种的饲草产量和营养含量,并在不同落叶间隔收获。该研究在旱季和雨季进行,采用3个因素(2x2x2)和4个重复的随机区组设计。第一个因素是两个不同的象草品种,分别为巴种和台湾,第二个因素是种植模式,包括间作和单作,第三个因素是收获年龄,包括50天和60天。结果表明,牧草品种、种植模式和收获年龄之间存在交互作用。与靛蓝间作并在60天收获的巴冲品种产生了最高的饲料鲜重和DM产量、ADF以及NDF含量和产量、CP产量和最高的承载力(p0.05),但在旱季,与靛蓝互作并在60d收获的巴冲品种产生的灰分和CP产量最高。台湾品种的ADF和NDF产量最高,在单一栽培和60天收获。研究结果表明,间作条件下,两个品种的象草均可与靛蓝配套栽培,60天的采收期将产生最高的养分产量和承载力。

COVID-19 and the increase in degenerative diseases are the reasons for the high consumption of functional foods. This study investigated the physicochemical, sensory, and functional characteristics of cheese enhanced with orthodox black tea. The primary research materials were 40 liters of fresh cow’s milk, orthodox black tea (OBT), mesophilic bacteria ( Lactococcus lactis ), animal calf rennet, and CaCl₂. An experimental completely randomized design (CRD) was employed in the study to four treatments, namely control (T 0 ), and the addition of 0.5% OBT (T 1 ), 1% OBT (T 2 ), 1.5% OBT (T 3 ), and 2% OBT (T 4 ). Each treatment was repeated four times and performed in duplicate. The observed variables were physical properties (colors and textures), chemical properties (moisture content, total solids, pH, and total titratable acidity), antioxidant activity, and sensory properties of cheese. The results showed that adding OBT up to 2% produced significantly different levels of pH, total titratable acidity, values (L*, a*, b*), hardness, antioxidant activity, and sensory properties of cheese. No significant difference was observed in the moisture content, total solids, and stickiness of cheese. Conclusively, incorporating OBT up to 2% in cheese making tends to increase the functional properties of cheese that include the a* value, total titratable acidity, and antioxidant activity, but it also decreases the L* and b* values, hardness, and pH value. The panelist’s preference was the highest for cow’s milk cheese with the addition of 0.5
新冠肺炎和退行性疾病的增加是功能性食品消费量高的原因。本研究对传统红茶强化干酪的理化、感官和功能特性进行了研究。主要研究材料是40升新鲜牛奶、正统红茶(OBT)、中温细菌(乳酸乳球菌)、动物小牛凝乳酶和氯化钙₂. 本研究采用实验性完全随机设计(CRD)对四种治疗方法进行研究,即对照(T0)和添加0.5%OBT(T1)、1%OBT(T2)、1.5%OBT(T3)和2%OBT(T4)。每次治疗重复四次,重复两次。观察到的变量是奶酪的物理特性(颜色和质地)、化学特性(水分含量、总固体、pH和总可滴定酸度)、抗氧化活性和感官特性。结果表明,添加2%的OBT会使奶酪的pH值、总可滴定酸度、值(L*、a*、b*)、硬度、抗氧化活性和感官特性显著不同。奶酪的水分含量、总固体含量和粘性没有显著差异。总之,在奶酪制作中加入2%的OBT往往会提高奶酪的功能特性,包括a*值、总可滴定酸度和抗氧化活性,但也会降低L*和b*值、硬度和pH值。小组成员对添加0.5的牛奶奶酪的偏好最高

The objective of the current study was to examine the effect of the utilization of acidified cogon grass (CG) ( Imperata cylindrica ) as a co-substrate for the anaerobic digestion of dairy cow manure (DCM). Four continuous stirred-tank reactor (CSTR) digesters with various substrate compositions, namely, T1 (100% DCM), T2 (95% DCM and 5% CG), T3 (95% DCM and 5% acidified CG using 4% H 2 SO 4 solution), and T4 (95% DCM and 5% acidified CG using Wuluh star fruit ( Averrhoa bilimbi L) filtrate), were operated. This study was conducted for 66 d or 3 hydraulic retention times (HRTs). Also, it evaluated the methane production of the digested slurry of each CSTR digester (batch-type) with five replications in each treatment. The results indicated that the methane production in T2, T3, and T4 in the unit of L/kg substrate increased by 35.52%, 41.95%, and 45.44%, respectively, compared with that in T1. Furthermore, the productions in T3 and T4 increased by 4.35% and 7.25%, respectively, compared with that in T2. The production from the slurries of CSTR digesters in units of L/kg substrate and L/kg volatile solid (VS) showed significantly different results (p<0.05).

The body-width linear traits of dairy cattle affect their production capacity, particularly milk yield characteristics. Even so, the prominent dairy cattle body width linked to the milk yield up to this point is not explicitly articulated. Therefore, this exploration aimed to identify the best body width characteristic related to production capacity and milk yields as a selection criterion. The investigation samples were 121 heads of Friesian Holsteins raised in Indonesia. The total measured body width of dairy cattle was eleven variables. All parameters were examined on a centimeter unit scale. R software version 4.2.1 is synchronized with RStudio to implement principal component analysis (PCA), Pearson’s correlation, and regression. The PCA uncovered the shoulder width (SHW), chest width (CHW), loin width (LNW), rump width (RMW), thurl width (TLW), pin width (PNW), and rear udder width (RUW) as significant elements of body width. Afterward, the highest relationship to milk yield characteristics was controlled by the rear udder width (RUW) and teat back-view width (TBW) traits serially. Due to the TBW being disqualified from the first principal component, its place is taken by the PNW trait. As an epilogue, exploiting the RUW trait as the main priority for the lactation cow selection scheme is strongly advocated. Meanwhile, the PNW trait is the initial priority for calves and heifers.
奶牛的体宽线性特性影响其生产能力,特别是产奶特性。即便如此,到目前为止,与产奶量相关的显著奶牛体宽并没有明确阐明。因此,本研究旨在确定与生产能力和产奶量相关的最佳体宽特征,作为选择标准。调查样本是在印度尼西亚饲养的121头弗里斯荷斯坦人。奶牛的总测量体宽为11个变量。所有参数都以厘米为单位进行检查。R软件版本4.2.1与RStudio同步,以实现主成分分析(PCA)、皮尔逊相关和回归。主成分分析发现,肩宽(SHW)、胸宽(CHW)、腰宽(LNW)、臀宽(RMW)、臀部宽度(TLW)、胸针宽度(PNW)和后乳房宽度(RUW)是身体宽度的重要因素。后乳宽度(RUW)和乳头后视宽度(TBW)性状与产奶特性的相关性最高。由于TBW不符合第一主成分,它的位置被PNW特征所取代。作为结语,强烈主张将利用RUW特性作为泌乳奶牛选择方案的主要优先事项。同时,PNW特性是小牛和小母牛的首要任务。

The broiler industry plays an important role in meeting the growing demand for animal protein. Ensuring favorable farming conditions are needed to maintain the meat supply, and theoretically, this can be improved through the implementation of Contract Farming (CF). CF grants farmers the privilege to predict quantities, prices, and reduce production risks. However, one of the key challenges in establishing CF is the cost efficiency and performance of farmers. This study aims to develop a cost function for farmers, identify factors contributing to inefficiency, and evaluate farmer performance. The purposive sampling method is employed to select broiler farmers participating in contract farming as the sample for this study. Primary data were collected through surveys. Stochastic frontier cost analysis is utilized to derive a broiler cost function while examining the causes of farm inefficiency and their relationship with farmers’ performance variables. The results indicate that the broiler cost function is significantly influenced by labor costs, the price of day-old chickens, feed expenses, and harvest tonnage. Meanwhile, the inefficiency effect is substantially influenced by farmer age, education, household size, experience, and mortality ratio (MR). Reducing the MR can increase broiler yield, directly improving cost efficiency and, thus farmers’ income. Nonetheless, a comprehensive approach that includes training, monitoring, feedback, and incentivization is needed to enhance farmer performance in broiler contract farming.
肉鸡行业在满足日益增长的动物蛋白需求方面发挥着重要作用。维持肉类供应需要确保有利的养殖条件,从理论上讲,这可以通过实施合同养殖(CF)来改善。CF赋予农民预测数量、价格和降低生产风险的特权。然而,建立CF的关键挑战之一是农民的成本效率和绩效。本研究旨在建立农民的成本函数,找出造成低效率的因素,并评估农民的绩效。本研究采用目的抽样方法,选取参与合同养殖的肉鸡农户作为样本。主要数据是通过调查收集的。本文利用随机前沿成本分析来推导肉鸡成本函数,同时考察农场效率低下的原因及其与农民绩效变量的关系。结果表明,人工成本、日龄鸡价格、饲料费用和收获吨位对肉鸡成本函数有显著影响。同时,农民的年龄、受教育程度、家庭规模、经验和死亡率对效率低下效应有显著影响。降低MR可以提高肉鸡产量,直接提高成本效率,从而提高农民的收入。尽管如此,需要一种包括培训、监测、反馈和激励在内的综合方法来提高肉鸡合同养殖中的农民绩效。

Dairy cows are one of the strategic livestock in Indonesia. However, increased dairy demand, which exceeds domestic dairy production, increases dairy import quantity. As dairy import increases, import tariff as an import restriction policy can be used to protect the sustainability of domestic dairy production. This study aimed to investigate the impact of import tariff policy on dairy supply and demand in Indonesia. This study used secondary data obtained from various official institutions. Factors determining dairy supply and demand were estimated using two-stage least squares (2SLS), and the impact of import tariff policy was estimated using a simultaneous equation system model. The empirical results indicate that the import tariff policy has a positive impact on dairy supply and a negative impact on dairy demand. Import tariffs were a factor determining the positive impact on dairy production, dairy cow population, and domestic dairy prices. The import tariff policy also had a negative impact on decreasing the quantity of dairy imports. It is concluded that import tariffs could be an important dairy import restriction policy to protect domestic dairy production and dairy producers in Indonesia.
奶牛是印尼的战略家畜之一。然而,乳制品需求的增加超过了国内乳制品产量,增加了乳制品进口量。随着乳制品进口的增加,进口关税作为一种进口限制政策可以用来保护国内乳制品生产的可持续性。本研究旨在探讨进口关税政策对印尼乳制品供需的影响。本研究使用了从各种官方机构获得的二手数据。采用两阶段最小二乘法(2SLS)估计乳制品供需的影响因素,采用联立方程系统模型估计进口关税政策的影响。实证结果表明,进口关税政策对乳制品供给有正向影响,对乳制品需求有负向影响。进口关税是决定对乳制品生产、奶牛数量和国内乳制品价格产生积极影响的一个因素。进口关税政策也对减少乳制品进口量产生了负面影响。综上所述,进口关税可以作为一项重要的乳制品进口限制政策,以保护印尼国内乳制品生产和乳制品生产商。

This study aimed to investigate the impact of import tariff policy on dairy supply and demand in Indonesia. This study used secondary data obtained from various official institutions. Factors determining dairy supply and demand were estimated using two-stage least squares (2SLS), and the impact of import tariff policy was estimated using a simultaneous equation system model. The empirical results indicate that the import tariff policy has a positive impact on dairy supply and a negative impact on dairy demand. Import tariffs were a factor determining the positive impact on dairy production, dairy cow population, and domestic dairy prices. The import tariff policy also had a negative impact on decreasing the quantity of dairy imports. It is concluded that import tariffs could be an important dairy import restriction policy to protect domestic dairy production and dairy producers in Indonesia.","PeriodicalId":42234,"journal":{"name":"Tropical Animal Science Journal","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45636437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
